DATA ALIGNMENT METHOD, MULTI-DEVICE SYSTEM AND NON-TRANSITORY COMPUTER READABLE STORAGE MEDIUM

A data alignment method and a multi-device system are provided. The multi-device system includes a host device and a client device. The data alignment method includes: by the client device, transmitting image data to the host device; by the host device, generating host-based spatial information of the client device in a host map of an environment established by the host device according to the image data; by the host device, transmitting the host-based spatial information to the client device; by the client device, generating data alignment information according to a difference between the host-based spatial information and client-based spatial information of the client device in a client map of the environment established by the client device; and by the client device, adjusting the client-based spatial information according to the data alignment information, to generate an aligned spatial information of the client device in the host map.
